BE1-49 Installation 4-1
NOTE
Be sure the relay case is hard-wired to earth ground with no smaller than 12 AWG
copper wire attached to the ground terminal on the rear of the relay case. When the
relay is configured in a system with other protective devices, always use a separate
lead to the ground bus from each relay.
SECTION 4 • INSTALLATION
GENERAL
When not shipped as part of a control or switchgear panel, the relays are shipped in sturdy cartons to prevent
damage during transit. Immediately upon receipt of a relay, check the model and style number against the
requisition and packing list to see that they agree. Visually inspect the relay for damage that may have
occurred during shipment. If there is evident damage, immediately file a claim with the carrier and notify the
Regional Sales Office, or contact Customer Service at Basler Electric, Highland, Illinois.
In the event the relay is not to be installed immediately, store the relay in its original shipping carton in a
moisture and dust free environment. When the relay is to be placed in service, it is recommended that the
following operational test be performed prior to installation.
RELAY OPERATING PRECAUTIONS
Before installation or operation of the relay, note the following precautions:
1. A minimum of 0.2 A in the output circuit is required to ensure operation of current operated targets.
2. The relay is a solid-state device. If a wiring insulation test is required, remove the connecting plugs and
withdraw the cradle from its case.
3. When the connecting plugs are removed the relay is disconnected from the operating circuit and will not
provide system protection. Always be sure that external operating (monitored) conditions are stable before
removing a relay for inspection, test, or service. Also, be sure that connecting plugs are in place before
replacing the front cover.
4. Be sure the relay case is hard wired to earth ground using the ground terminal on the rear of the unit. Use
a separate ground lead to the ground bus for each relay.
DIELECTRIC TEST
In accordance with IEC 255-5 and ANSI/IEEE C37.90, one minute dielectric (high potential) tests as follows:
All circuits to ground: 2,121 Vdc
Input to output circuits: 1,500 Vac or 2,121 Vdc.
MOUNTING
Relay outline dimensions and panel drilling diagrams are supplied in Figures 4-1 through 4-10.
CONNECTIONS
Incorrect wiring may result in damage to the relay. Be sure to check model and style number against the
options listed in the Style Number Identification Chart before connecting and energizing a particular relay.
Connections should be made with 14 AWG stranded wire or better. Typical external connections are shown
in Figure 4-11 . For internal connections refer to Section 3,
